I have been playing RoF since its release in 2009, and it has improved so much since `09, i love this game.
Most people who have written give it a bad review because of the DLC, and yeah i can understand that, but what they don`t realize is that when you purchased the base game in `09 it came with +- 6-8 planes, 1 map, no single player campaign, etc etc.
Then after 2-3 months the first 2 plane dlc would come out, and all the Rof folks would jump on it, because it adds to the game.
Now if you start new.. then yeah you have a big amount of planes to buy, but its not a reason to give the game a bad review.
For the game, I think it has the best damage engine in a flight sim to date, just taking off and diving back into the ground with time set to -10 is enough enjoyment to keep you busy for hours.
I love the single player campaign, as it puts you as a rookie pilot in the middle of the war, and it lets you choose which period of the war, which side, which plane etc etc.
Only thing i dislike is that you will not fly with the famous WW1 aces, you can encounter them in the air, but no matter how many times you fly with Jasta 11 you will not see Voss, Richthofen, or Udet..something that the game really needs.
Also a issue for me is that when you switch squadrons the kill tally list is empty for the AI flyers..as if the war did not exist for them till you joined.
But that's where for me the negative ends for this game.
I will give this game AAA+ and recommend it to anyone that loves the period and flightsims, and i would advice getting the Base game and the Acepack to start with (i own the non steam game and steam game, but on steam i only have those 2 pieces of the package).
